 When receiving a response, the Orb Java SDK will deserialize it into instances of the typed model classes. In rare cases, the API may return a response property that doesn't match the expected Java type. If you directly access the mistaken property, the SDK will throw an unchecked `OrbInvalidDataException` at runtime. If you would prefer to check in advance that that response is completely well-typed, call `.validate()` on the returned model.
